Well, with my Prismacolor markers getting kinda dry, I decided to get a full set of Copic warm and cool grays. I scored them on sale, which was excellent, although they still cost a pretty penny. Not like going out and getting a new set of Crayola markers for my four-year-old! I like them a lot better than the Prismacolor markers, especially because of the brush nib (I got the Copic Sketch type). They lay down much more like watercolours, or at least how I imagine watercolours lay down, since I only paint with acrylics. I haven't found the perfect paper for using them on yet, as the cardstock I am using right now bleeds a little too much for my liking. I have a Wonder Woman image in my head that I want to try and do in a larger format (like 11x14), so I may start that soon. I needed to get a feel for the Copics before I endeavoured to do something like that. So far they are awesome!
